DAB tetrahydrochloride hydrate is a water soluble form of 3-3'-diaminobenzidine and is used to stain for peroxidase activity. The intensity of DAB staining can be increased with the addition of cobalt, nickel or silver ions.

Natamycin is a macrolide polyene antifungal agent isolated from Streptomyces species. It is effective against fungi such as Candida, Aspergillus, Cephalosporium, Fusarium, and Penicillium. Natamycin works by binding ergosterol and preventing carbohydrate and amino acid transport. Unlike other polyen...

Thiostrepton is a cyclic peptide antibiotic isolated from Streptomyces azureus. It targets a wide variety of gram-negative and gram-positive bacteria, especially those causing skin infections. It has been used as a marker for selection of recombinant Streptomyces cultures. Additionally, thiostrepton...

Glufosinate or Glufosinate ammonium a broad-spectrum herbicide that acts as a competitive inhibitor of glutamine synthetase.Glutamine synthetase plays an important role in plant nitrogen metabolism. Its actions lead to the formation of glutamine; however, when inhibited by phosphinothricin, a rapid...

RMP, Rifampin Rifampicin is a broad-spectrum antibiotic known for its efficacy against tuberculosis and other infections caused by Mycobacterium species. This semisynthetic antibiotic has also been shown to work against methicillin-resistant Staphylococcus aureus (MRSA), to activate nuclear pregnane...
